Kevin Jepsen and Rich Thompson now appear in line to make the club with Bobby Cassevah (labrum tear) and Michael Kohn (forearm strain) starting the season on the DL.
In four appearances (one start) this spring, Bell posted a 3.72 ERA. He struck out five and walked five.
On Friday, the Angels informed 39-year-old Jason Isringhausen he would make the club, leaving Bell, Thompson and Jepsen competing for three spots.
Now it appears the Angels bullpen is set with right-handers Isringhausen, Thompson, Jepsen, LaTroy Hawkins and Jordan Walden, and lefties Scott Downs and Hisanori Takahashi.
